A San Diego doctor who lost his license for performing crude sex-change operations was sentenced to 15 years to life for amputating the leg of an elderly New Yorker to satisfy the patient’s sexual fetish.

John Ronald Brown, 77, was convicted of second-degree murder in October in the 1998 death of 79-year-old New Yorker Philip Bondy.

Bondy had paid Brown $10,000 to amputate a leg to satisfy his “apotemnophilia,” a rare fetish involving sexual gratification from the removal of a limb.

Two days after the amputation, Bondy died of gangrene poisoning at a San Diego hotel. Prosecutor Stacy Running charged that Brown “just chopped off” the elderly New Yorker’s leg.

Running said that after Brown at his Tijuana clinic amputated Bondy’s leg below the knee, he left Bondy at the hotel.

Bondy called Brown the next day to report bleeding from the stump. Brown rewrapped the leg and suggested Bondy take more pain medication.

Before his trial, Brown pleaded guilty to practicing medicine without a license – charges arising from seven shoddy sex-change operations. Brown lost his doctor’s license in 1977 because of his crude operations.
